Defrosting water draining device for refrigerator

Abstract

A refrigerator having a draining unit to drain defrost water, produced by both an evaporator and a refrigerant pipe, to an outside of a cabinet thereof. The refrigerator having a storage compartment defined in the cabinet, with an evaporator provided in the cabinet to supply cool air to the storage compartment. A first defrost water tray having a first drain port is positioned under the evaporator to drain the defrost water produced by the evaporator. A second defrost water tray is positioned under both the refrigerant pipe extending to the evaporator and the first drain port of the first defrost water tray, so as to guide a draining of the defrost water produced by the refrigerant pipe and the defrost water drained from the first drain port of the first defrost water tray. The second defrost water tray having a second drain port which is connected to a drain guide hose.

Description

technical field [0001] The present invention generally relates to a refrigerator, and more particularly, to a refrigerator having a drain for draining defrosted water generated by an evaporator and a refrigerant pipe to the outside of the cabinet. Background technique [0002] Generally, a refrigerator is a machine that generates cool air through a heat exchange process performed by an evaporator. Cool air is then supplied to the storage chamber to keep various foods stored in the storage chamber cool, thereby maintaining the freshness of the food for a required period of time. During refrigerator operation, high-humidity air circulates within the refrigerator cabinet, starting from the storage compartment, passing through the evaporator, and returning to the storage compartment. During operation, high humidity air repeatedly contacts the cold evaporator, causing frost to accumulate on the evaporator surface. After a period of time, the frost layer on the surface of the ev...

AI Technical Summary

Problems solved by technology

[0003] However, the problem with conventional refrigerators is that the defrost heater is installed around the evaporator, and the defrost water tray is installed under the evaporator

As a result, the refrigerant tubes extending from the condenser to the evaporator cannot be effectively defrosted

[0004] Also, conventional refrigerators do not have a defrost water tray under the refrigerant line from the condenser to the evaporator

Therefore, when defrosting the refrigerant pipe, the defrosted water from the refrigerant pipe may flow into the storage chamber
